Wikileaks publishes 'biggest ever leak of secret cia documents'

The US intelligence agencies are facing fresh embarrassment after WikiLeaks published what it described as the biggest ever leak of confidential documents from the CIA detailing the tools it uses to break into phones, communication apps and other electronic devices.

The thousands of leaked documents focus mainly on techniques for hacking and reveal how the CIA cooperated with British intelligence to engineer a way to compromise smart televisions and turn them into improvised surveillance devices.

The leak, named “Vault 7” by WikiLeaks, will once again raise questions about the inability of US spy agencies to protect secret documents in the digital age. It follows disclosures about Afghanistan and Iraq by army intelligence analyst Chelsea Manning in 2010 and about the National Security Agency and Britain’s GCHQ by Edward Snowden in 2013.
